摘　　要：针对220 kV氧化锌避雷器直流1 mA参考电压U及0.75U下泄露电流测试时遇到的工作量大、拆接耗时长、耗资大等困难,通过三种不同接线方式的对比分析,确定了串联电阻微安表的试验方法。经过理论分析和大量的现场对比试验,证明该方法可以实现不拆引线试验,并且效果良好。在实际工作既节省了人力物力,又降低了风险等级,为顺利完成220 kV氧化锌避雷器试验创造了条件。This study introduces the difficulties of heavy workload, long disassembly time and high cost in the test of 1 mA DC reference voltage Uand 0.75Uleakage current of 220 kV zinc oxide lightning arrester and determines the test method of series resistance microammeter through comparative analysis of three different wiring modes. Based on the theoretical analysis and a lot of real comparative tests, it is proved that this method can realize the test without dismantling the lead and the effect is good. It not only saves human and material resources, but also reduces the risk level and lays the foundations for the successful completion of 220 kV lightning arrester test in the following experiment.
